SLED-RUNNER.

SPECIFICATION forming part of Letters Patent N 0. 743,902, datedNovember 10, 1903. Applicationfiled December 17,1802. Serial No,135,619. (No model To LZZ whom it may concern:

Be it known that 1, JAMES MANN, a subject of the King of Great Britain,residing at Yorkton, NorthJVest Territory, and Dominion of Canada, haveinvented a new and useful Sled- Runner, of which the following is aspecification.

- This invention relates more particularly to sled-runners, the objectbeing to provide a brace that will be verystrong and prevent thebreakage to which the runners are so liable. It is also the aim toprovide a structure which can be applied to ordinary runners now ingeneral use either before or after a break has occurred, in the latterinstance having proven entirely efficient in repairing the runner andmaking it strong and rigid.

.The preferred form of construction has been illustrated in theaccompanying drawings and is described in the following specification.An inspection of the claims will show, however, that the embodiment setforth is open to various changes and modifications.

In the drawings, Figure 1 is a side elevation of a runner, showing thebrace applied thereto. Fig. 2 is a vertical longitudinal see- Fig. 3 isa transverse section, and Fig. t is a detail perspective view, of thebrace.

Similar numerals of reference designate corresponding parts in all thefigures of the drawings. I

The runner-body is designated by the reference-numeral l0 and may be ofany wellknown form, having on its lower edge the usual metallic shoe 11.Upon an intermediate portion of the runner is arranged a beamsupport orknee 12,. that can be of any desirable construct-ion, no claim beingmade to any of these features per se. The invention as illustrated bythe present embodiment consists of spaced truss-rods 13, that arearranged longitudinally of the runner on opposite sides of the same andextending diagonally across the side faces. These braces are secured inthe following manner:

An car 14 is arranged upon the upper edge of the forward end of therunner, being socured thereto by bolts 15, which pass through the runnerand also serve for securing the shoe in place. Upon the upper edge ofthe rear end of said runner is arranged a clip 16,

having an upstanding transversely-disposed flange 17 and fastened inplace by vertical bolts 18, which, like the bolts 15, pass through therunner-body and the shoe. Arranged transversely across an intermediateand lower portion of the runner, preferably beneath the beam-support orknee 12, is a stirrup 19, which is located between the shoe and thebody, the latter having a seat 20 to receive the same. This stirrup hasat its ends upstanding eyes 21, whichare thus located on opposite sidesof the runner-body, as clearly shown in'Fig. 3. The brace-rods 13 areconnected at one end by a cross-piece 22, which is passed through thecar 14, while the other ends of said rods are threaded, as shown at '23,and are passed through the flange 17 of the clip. Tension-nuts 24,screwed upon said threaded ends, bear against the flange.

In view of the fact'that it is a very common occurrence for the runnersto break transversely and substantially along the line 3 3 of Fig. 2 itwill be apparent that the bracerods constitute trusses, which willsecurely prevent such accidents. The improvement may be readily appliedto runners now in use either before or after breaks have occurred, andfrom actual experience it has been found that in the latter case bytightening the rods through the medium of the tension-nuts therunner-body can be brought back to proper place and will be very strongand rigid. The parts are extremely simple, so that the brace can bemanufactured at small cost, and the bolts which hold the shoe in placemay also be employed for fastening the clip and ear, as alreadydescribed.

From the foregoing it is thought that the construction,operation,andmany advantages of the herein-described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is-- Ice 1. The combination with asled-runner, of

a knee, and a truss-brace havingan interme diate portion secured to therunner beneath the knee and extending in opposite directions, and meansfor securing the oppositely-extending portions of the brace to therunner at points higher than the intermediate attachment thereof.

2. The combination with a sled-runner, of a knee and a truss-bracehaving an intermediate portion secured to the lower portion of therunner beneath the knee and extending in opposite directions diagonallyof said runner, and means for securing the ends of the truss to therunner on opposite sides of the knee.

3. The combination with a sled-runner, of a knee, and a truss-bracehaving an intermediate portion secured to the lower portion of therunner beneath the knee and extending in opposite directions diagonallyof the runner, being secured at separated points to the upper portionthereof on opposite sides of the knee.

4. The combination with a sled-runner, of a knee mounted on anintermediate portion thereof, and a truss-brace comprising spaced rodslocated on opposite sides of the runner, said rods having intermediateportions secured to the lower portion of the runner beneath the knee andextending in opposite directions diagonally of said runner, beingsecured at separated points to the upper portion thereof on oppositesides of the knee.

5. The combination with a sled-runner, of a knee mounted on anintermediate portion thereof, a stirrup extending across the lowerportion of the runner directly beneath the knee and having eyes onopposite sides of said runner, and a truss-brace comprising rods 10-cated'on opposite sides of the runner and havingintermediate portionspassingthrough the eyes of the stirrup, the ends of said rod beingattached to the runner on opposite sides of the knee.

6. The combination with a sled-runner, of an ear secured to the upperface thereof contiguous to one end, a stirrup extending across the lowerand intermediate portion of the runner and having eyes at its ends, aclip attached to the other end of the runner, bracerods extendinglongitudinally along and diagonally across the opposite side faces ofthe runner, said rods passing through the eyes of the stirrup,cross-piece connecting the rods-at one end and passing through the ear,the other ends of said rods being threaded and passed through the clip,and tension-nuts screwed upon said ends.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.

JAMES MANN.
